[0061] The water squeezing device 4 in the utility model, including water squeezing sleeve 5, water squeezing frame 6 and liquid spraying mechanism 7, specifically, such as Figure 2 The top of the water squeezing sleeve 5 is provided with a sleeve, which can be sleeved on the outer surface of the mop rod 1 and move up and down along the mop rod 1, the bottom of the water squeezing sleeve 5 is fixedly connected with the water squeezing frame 6, and the lower end of the water squeezing sleeve 5 can also be a sleeve sleeved on the outer surface of the mop rod 1; such as Figure 3 The lower end of the water squeezing sleeve 5 can also be a connecting rod 9 extending up and down on the outer side of the mop rod 1. Such as Figure 4 The water squeezing frame 6 is provided with a squeezing opening 10 and a rod opening 11 penetrating up and down, the squeezing opening 10 and the rod opening 11 are transversely communicated, the squeezing opening 10 is used for the mop head 2 and the wiping article 3 to pass up and down during cleaning, the rod opening 11 is sleeved on the outer surface of the mop rod 1, during the process that the mop head 2 and the wiping article 3 enter the squeezing opening 10, the front and rear sides of the water squeezing frame 6 can simultaneously support the mop rod 1, the mop head 2 and the wiping article 3, and the upper end of the water squeezing frame 6 is fixedly connected with the lower end of the water squeezing sleeve 5 to form a whole water squeezing device 4.

[0062] In the utility model, the liquid spraying mechanism 7 includes a pressing part 12, a liquid storage cavity 13 and a liquid spraying opening 14, the liquid storage cavity 13 is used for storing cleaning liquid, the pressing part 12 is used for controlling the cleaning liquid to be sprayed out from the liquid spraying opening 14 and sprayed on the wiping article 3 or the ground, the upper end of the water squeezing sleeve 5 forms a water squeezing handle 15 for the hand of a user to hold to push and pull the water squeezing device 4 up and down, the liquid spraying mechanism 7 is installed on the water squeezing handle 15 or the water squeezing sleeve 5 is located at a position below the water squeezing handle 15 to provide a space for the hand of the user to hold, and generally one hand of the user holds the upper end of the mop rod 1 and the other hand holds the water squeezing handle 15 when the flat mop is used to clean the wiping article 3, and the water squeezing handle 15 is pushed and pulled up and down to realize the relative movement between the water squeezing device 4 and the wiping article 3 for cleaning. The position of the liquid spraying mechanism 7 is arranged to facilitate the user to hold the water squeezing handle 15 to push and pull the water squeezing device 4 to clean the wiping article 3, and the liquid spraying mechanism 7 can be controlled to spray cleaning liquid on the wiping article 3 at the same time to further clean or moisten the wiping article 3, so that the work of spraying liquid on the wiping article 3 and cleaning the wiping article 3 can be simultaneously performed by single-handed operation.

[0063] Specific use mode is, such as Figure 5The wringing device 4 is positioned at the high position of the mop handle 1. The mop head 2 is rotated to a position perpendicular or inclined to the mop handle 1. At this time, the flat mop can be used to clean the floor. When the mop head 2 is rotated to a position approximately parallel to the mop handle 1, the wringing device 4 is pushed downwards. The mop head 2 and the wiping material 3 enter the squeezing port 10 upwards. The squeezer 8 cleans the wiping material 3. At the same time, the pressing part 12 is operated to spray cleaning liquid onto the wiping material 3 to improve the cleaning effect.

[0064] In this invention, the direction facing the wiping object 3 is the forward direction, and the direction away from the wiping object 3 is the rear direction. The squeezer 8 and the spray nozzle 14 are both located in front of the squeezing device 4. Preferably, when the wiping object 3 is parallel to the mop handle 1, the squeezer 8 and the spray nozzle 14 are both located in front of the wiping object 3, so that the squeezer 8 can contact the wiping object 3 for cleaning and squeezing, and the moving resistance between the squeezer 8 and the wiping object 3 will not be too large, and it can also provide space for the spray nozzle 14 to spray liquid onto the wiping object 3. Example 1

[0065] In this embodiment, the wringer sleeve 5 and the main body of the wringer frame 6 are integrally molded from plastic material. The lower end of the wringer sleeve 5 is provided with a clearance groove 16 for the mop head 2 to move. The main body of the wringer frame 6 is equipped with a squeezer 8 and a support 17 to jointly hold the mop head 2. The mop handle 1 and the mop head 2 can pass through the handle opening 11 and the squeezing opening 10 at the same time. The squeezer 8 cleans or squeezes water from the wiping material 3 that enters the squeezing opening 10.

[0066] In this embodiment, as Figure 7 The spraying mechanism 7 includes a housing 18, which has a cavity to form a liquid storage chamber 13 or a liquid storage chamber 13 installed inside the housing 18. The pressing part 12 and the spray nozzle 14 are also provided on the housing 18, so that the housing 18, the pressing part 12, the liquid storage chamber 13 and the spray nozzle 14 form a spraying module as a whole. The pressing part 12 can be installed on the liquid storage chamber 13 and then installed on the housing 18 at the same time as the liquid storage chamber 13. The spray nozzle 14 can be a separate component or a spraying port can be provided on the housing 18. The squeezing sleeve 5 has an installation platform 19 on or below the squeezing handle 15. The spraying mechanism 7 is installed on the squeezing sleeve 5 through the installation platform 19.

[0067] Preferably, in order to facilitate the maintenance and replacement of the liquid spraying mechanism 7, the pressing part 12, the liquid storage cavity 13, the liquid spraying port 14 and the shell 18 are assembled into a complete liquid spraying module during production and installation, and then the liquid spraying module is installed on the installation platform 19. Since liquid spraying inspection needs to be performed on each liquid spraying mechanism 7 during production and assembly or inspection, the liquid spraying mechanism 7 that passes the inspection can be installed on the installation platform 19, while the liquid spraying mechanism 7 that fails the inspection needs to be repaired or destroyed. The complete liquid spraying module is provided, and the liquid spraying module can be individually subjected to liquid spraying inspection. In the prior art, the liquid spraying mechanism is associated with the wringing device, that is, part of the components in the wringing device form part of the components in the liquid spraying mechanism. During production and inspection, the complete wringing device or even the complete flat mop needs to be subjected to liquid spraying inspection. Since the components to be inspected are large, the inspection is more troublesome and the inspection efficiency is low. Compared with the liquid spraying mechanism in the prior art, the assembly, inspection and repair of the liquid spraying mechanism 7 and the wringing device 4 in the embodiment are simpler and the cost is lower.

[0068] In the embodiment, as shown in Figure 2 and Figure 5 , the liquid spraying mechanism 7 and the wringing frame 6 are independent, which includes functional independence and structural independence. The functional independence means that the liquid spraying function of the liquid spraying mechanism 7 and the cleaning and wringing function of the wringing frame 6 are independent. Whether the liquid spraying mechanism 7 and the wringing device 4 are installed as a whole or not, the liquid spraying function of the liquid spraying mechanism 7 and the wringing function of the wringing frame 6 can be realized independently. Preferably, the liquid spraying mechanism 7 is integrally detachably installed on the wringing sleeve 5. When the liquid spraying mechanism 7 is installed on the wringing sleeve 5, the flat mop can simultaneously have the liquid spraying function and the cleaning and wringing function of the wiping material 3. When the liquid spraying mechanism 7 is detached, the flat mop still has the cleaning and wringing function of the wiping material 3. The detached liquid spraying mechanism 7 can still be used as a liquid spraying bottle to spray liquid on other objects.

[0069] As shown in Figure 5 , the structural independence means that, except for the connection relationship of the wringing sleeve 5, the whole of the liquid spraying mechanism 7 and the whole of the wringing frame 6 have no other connection relationship. The whole of the liquid spraying mechanism 7 is located directly above the wringer 8, and the liquid spraying mechanism 7 and the wringing frame 6 have no waterway connection and control connection. The liquid spraying mechanism 7 and the wringing frame 6 or the liquid spraying port 14 and the wringing frame 6 have a spacing, and the spacing forms a spraying area 20.

[0070] In the above embodiment, as shown in Figure 5, the housing 18 extends to the direction of the wringing frame 6, the liquid spraying port 14 is arranged at the end of the housing extension section, the housing extension section forms the liquid storage cavity 13, that is, the spraying direction of the liquid spraying port 14 is substantially parallel to the extension direction of the mop rod 1, when the wringing device 4 moves downward along the mop rod 1, the mop head 2 and the wiping article 3 relatively move upward, the wiping article 3 passes through the pressing opening 10 upward into the spraying area 20, until the bottom of the liquid spraying mechanism 7 moves to the height close to or at least partially coincides with the top of the wiping article 3, during the process of the wiping article 3 entering and leaving the spraying area 20, or when the wiping article 3 moves to the preset highest position, the pressing part 12 controls the liquid spraying port 14 to spray the cleaning liquid to the spraying area 20 for self-cleaning of the wiping article 3.

[0071] Generally, the flat mop directs the wiping article 3 upward to the faucet when cleaning the wiping article 3, based on the use habit, the liquid spraying port 14 in the embodiment is arranged exposedly, and does not fit with the wiping article 3, the cleaning liquid can fall on the wiping article 3 under the action of the spraying force and gravity.

[0072] As Figure 6 , in order to avoid the situation that the user accidentally touches the pressing part 12 or sprays the liquid in the case that the wiping article 3 is downward, and the cleaning liquid cannot be sprayed to the wiping article 3, the liquid spraying port 14 can also be arranged obliquely, so that the cleaning liquid can still move to the wiping article 3 according to its inertia after leaving the liquid spraying port 14, so that the cleaning liquid can be sprayed to the wiping article 3 regardless of the control angle of the flat mop.

[0073] Compared with the liquid spraying port 14 arranged to fit or contact the wiping article 3, the cleaning liquid in the embodiment first passes through the external air after leaving the liquid spraying port 14, and then falls on the wiping article 3, whether the liquid spraying mechanism 7 sprays liquid and the size of the spraying amount can be observed through the movement of the cleaning liquid in the external air and the situation of falling on the wiping article 3, so as to adjust the spraying size of the liquid spraying mechanism 7 and supplement the cleaning liquid in the liquid storage cavity 13 by the user. At the same time, the way that the liquid spraying port 14 contacts the wiping article 3 sprays liquid, the dust and dirt on the wiping article 3 are easy to block the liquid spraying port 14, which affects the spraying effect.

[0074] In order to illustrate the independent situation of the liquid spraying mechanism 7 and the wringing frame 6 and the position of the spraying area 20, as Figure 5 and Figure 8, the length of the wringing device 4 is X, the length of the mop head 2 or the wiping material 3 is Y, the length of the distance between the liquid spraying port 14 and the wringing frame 6 is Z, and the space where the length Z is located is the spraying area 20, which is used for the movement of the spraying process of the cleaning liquid and for the user to observe the spraying state. The length X is greater than the length Y, so as to avoid the contact between the hand and the wiping material 3 during the movement of the wringing device 4. In order to avoid the sprayed cleaning liquid from falling on the wringing frame 6 or even falling on the ground beyond the wringing frame 6, the length Z in the embodiment is set to be greater than one half of the length Y. The lengths X, Y and Z in the embodiment are all the horizontal lengths in the state of the flat plate mop as shown in the drawing. Figure 8 It is to be noted that if the lengths of the wringing device 4, the mop head 2 and the wiping material 3 are adjustable or foldable, only the lengths of the wringing device 4, the mop head 2 and the wiping material 3 in the normal cleaning and wringing state are compared. The length Z generally refers to the distance between the top of the wringing frame 6 (excluding the wringing sleeve 5) and the part of the liquid spraying mechanism 7 closest to the wringing frame 6. For example, if most of the parts of the wringing device 4 are located above the wringing sleeve 5 and the liquid spraying port 14 is arranged in the wringing frame 6, the length Z is zero or even a negative length.

[0075] In the above embodiment, when the wringing device 4 moves to the lowest position relative to the mop head 2, i.e. the mop head 2 and the wiping material 3 move to the highest position, the liquid spraying mechanism 7 and the wiping material 3 have an overlapping area along the plane perpendicular to the mop rod 1, or they are always not overlapping, as shown in Figure 5 and Figure 8 , which are schematic diagrams of the ways in which the liquid spraying mechanism 7 and the wiping material 3 have an overlapping area and are always not overlapping, respectively.

[0076] In other embodiments, the liquid spraying port 14 can also be arranged on the side of the housing 18 close to the wiping material 3, and the liquid spraying port 14 sprays liquid onto the wiping material 3 when the liquid spraying port 14 moves to overlap with the wiping material 3 at any position. In this spraying way, a space for the mop head 2 and the wiping material 3 to enter is arranged between the wringing sleeve 5 and the liquid spraying mechanism 7, and the space forms the spraying area 20. The thickness of the spraying area 20 is adapted to the thickness of the mop head 2 plus the wiping material 3. When the liquid spraying port 14 partially overlaps with the wiping material 3, the liquid spraying port 14 is attached to the wiping material 3 or there is a liquid spraying gap between the liquid spraying port 14 and the wiping material 3. In this spraying way, the area of the wiping material 3 that can be sprayed is related to the overlapping length of the movement of the wiping material 3 and the liquid spraying port 14 and the width of the liquid spraying port 14. If there is an area that is not sprayed with cleaning liquid, the squeezer 8 moves relative to the wiping material 3 to evenly spread the cleaning liquid and bring the cleaning liquid to the area that is not sprayed, so as to realize that the wiping material 3 as a whole receives the cleaning liquid.

[0077] Compared with the existing liquid spraying mechanism, the liquid spraying mechanism 7 in the embodiment is more integrated and simple. The water jacket 5 and the water squeezing frame 6 do not need to be provided with a separate cavity for installing a water channel, thereby simplifying the installation structure of the water squeezing device 4 and the liquid spraying mechanism 7, improving the production assembly efficiency. Meanwhile, the water channel of the liquid spraying mechanism 7 is independent of the water jacket 5 and the water squeezing frame 6, which can avoid the water channel in the water jacket 5 and the water squeezing frame 6 being bent or blocked due to the pressure or tension caused by the up-down movement of the water squeezing device 4. Of course, the liquid spraying mechanism 7 in the embodiment is provided as an independent liquid spraying module, and the water channel can not be provided, and the cleaning liquid can be directly sprayed from the liquid storage cavity 13 to the spraying port 14.

[0078] In the above embodiment, the part of the water squeezing frame 6 located at the front side of the squeezing port 10 has a certain thickness, which can increase the overall strength of the water squeezing frame 6, so as to avoid the deformation of the water squeezing frame 6 when the mop head 2 and the wiping material 3 enter the squeezing port 10. The space formed by the thickness of the front side of the water squeezing frame 6 can be used for installing the squeezer 8.

[0079] Preferably, the front side of the water squeezing frame 6 is provided with an intercepting portion 21 extending to the front side, which can block the liquid about to leave the wiping material 3, so as to avoid the liquid moving to the ground, wall surface or other positions where the liquid is not needed. In the embodiment, the intercepting portion 21 is perpendicular to the wiping material 3 during the squeezing or is inclinedly arranged with the front end of the intercepting portion 21 being higher and the rear end being lower. If the intercepting portion 21 is arranged with the front end being lower and the rear end being higher, no matter whether the inclined surface is a straight surface or an arc surface, the cleaning liquid is easily guided to the outside along the extension direction of the intercepting portion 21. In the embodiment, the intercepting portion 21 can be arranged in the following ways.

[0080] The first way is as shown in Figure 9 , the intercepting portion 21 is arranged at the front side of the water squeezing frame 6, that is, a raised portion is arranged at the front side of the water squeezing frame 6, and the surface angle region between the intercepting portion 21 and the water squeezing frame 6 forms a temporary storage area 22. The intercepting portion 21 can also be arranged in a perpendicular or inclined way to the wiping material 3. In order to prevent the liquid in the temporary storage area 22 from flowing out and being used for cleaning the wiping material 3, any one or more of the three positions of the intercepting portion 21, the water squeezing frame 6 and the space between the intercepting portion 21 and the water squeezing frame 6 can be provided with a backflow hole 23. The liquid in the temporary storage area 22 can flow into the squeezing port 10 through the backflow hole 23 to clean the water squeezing frame 6, the squeezer 8 or the wiping material 3. The external cleaning water can also enter the water squeezing frame 6 through the backflow hole 23 to clean the water squeezing frame 6, the squeezer 8 or the wiping material 3.

[0081] The second way is as shown in Figure 10, intercepting part 21 is arranged on the top of the front side of the squeezing frame 6, or the top of the front side of the squeezing frame 6 is formed into the intercepting part 21, the intercepting part 21 blocks part of the liquid and forms a temporary storage area 22 above the intercepting part 21; in the inclined arrangement of the intercepting part 21, the angle area between the intercepting part 21 and the wiping material 3 forms the temporary storage area 22, which can intercept and store more liquid, and in the general use habit, the inclined intercepting part 21 is more vertical, and the flow guiding effect is better. Similarly, the intercepting part 21 can also be provided with a reflux hole 23 penetrating up and down, and the liquid in the temporary storage area 22 can flow into the squeezing opening 10 or the squeezing frame 6 through the reflux hole 23 to clean the wiping material 3, and the external cleaning water can also enter the squeezing frame 6 through the reflux hole 23 to clean the squeezing frame 6, the squeezer 8 or the wiping material 3.

[0082] Thirdly, as shown in FIG. 6, the intercepting part 21 is arranged on the top of the front side of the squeezing frame 6, and the intercepting part 21 is arranged on the top of the front side of the squeezing frame 6. Figure 11 Meanwhile, the two kinds of intercepting parts 21 are arranged at the same time, so that the intercepting effect is better.

[0083] Preferably, the intercepting part 21 adopts a flat surface or a shape in which the rear end is lower than the front end, so as to improve the intercepting and flow guiding effects.

[0084] In the above embodiment, during the downward movement of the squeezing device 4 relative to the wiping material 3 in the process of cleaning and squeezing water of the flat mop, the squeezer 8 squeezes the wiping material 3, and the water in the wiping material 3 is driven downward by the squeezer 8. The squeezing frame 6 is provided with a drainage hole 24 below the intercepting part 21, the drainage hole 24 and the reflux hole 23 are independent, and the water generated by the cleaning and squeezing of the wiping material 3 by the squeezer 8 flows outwards through the drainage hole 24 and the lower part of the squeezing opening 10.

[0085] Specifically, as shown in FIG. 7, the squeezer 8 is provided with a slanting track 25, and the two ends of the squeezer 8 are movably installed on the slanting track 25 through a convex column 26. Figure 12 During the cleaning or squeezing water, the squeezer 8 moves in the direction of entering the squeezing opening 10, and the interference depth of the squeezer 8 with the wiping material 3 is larger, so as to clean and squeeze water of the wiping material 3. Figure 10 During the cleaning or squeezing water, the squeezer 8 moves in the direction of entering the squeezing opening 10, and the interference depth of the squeezer 8 with the wiping material 3 is larger, so as to clean and squeeze water of the wiping material 3. Figure 9 During the cleaning or squeezing water, the squeezer 8 moves in the direction of entering the squeezing opening 10, and the interference depth of the squeezer 8 with the wiping material 3 is larger, so as to clean and squeeze water of the wiping material 3.

[0086] In other embodiments, the squeezer 8 can be fixed with the squeezing frame 6 or the movable state of the squeezer 8 is opposite to the above-mentioned manner, the squeezer 8 cleans and squeezes water of the wiping material 3 when the squeezing device 4 moves upwards, and the water squeezed out of the wiping material 3 flows outwards through the reflux hole 23, so that the reflux hole 23 has the dual functions of outward drainage and inward liquid discharge in different use conditions. Embodiment 2

[0087] The difference between this embodiment and Embodiment 1 is that the liquid spraying mechanism 7 uses a liquid pump to discharge liquid.

[0088] In this embodiment, the liquid spraying mechanism 7 comprises a pressing portion 12, a housing 18, a liquid spraying port 14 and a liquid pump 27, the housing 18 is provided with a cavity and a space for mounting the pressing portion 12, the cavity forms a liquid storage cavity 13, the liquid pump 27 is mounted between the pressing portion 12 and the liquid storage cavity 13 or in the liquid storage cavity 13, the bottom of the housing 18 or the side close to the wiping article 3 is provided with the liquid spraying port 14, and the pressing portion 12 drives the liquid pump 27 to spray the cleaning liquid in the liquid storage cavity 13 out of the liquid spraying port 14 during use.

Figure 13 The use mode of the liquid pump 27 is that the pump core 29 moves into the pump shell 28 to extrude the air in the pump core 29, the liquid inlet valve 31 is closed, the liquid outlet valve 33 is opened, and the air in the pump shell 28 leaves through the liquid outlet pipeline 32; the spring 35 drives the pump core 29 to move outwardly to reset, the volume between the pump core 29 and the pump shell 28 becomes larger, the pressure becomes smaller, the liquid outlet valve 33 is closed, the liquid inlet valve 31 is opened, and the pressure difference between the liquid outlet valve 33 and the liquid storage cavity 13 causes the cleaning liquid in the liquid outlet cavity to enter the liquid outlet valve 33 through the liquid inlet pipeline 30 and the liquid inlet valve 31, and the liquid inlet valve 31 completes the liquid suction; the pump core 29 moves into the pump shell 28 again to change the liquid pressure in the liquid pump 27, the pressure difference between the liquid pump 27 and the outside causes the liquid inlet valve 31 to be closed and the liquid outlet valve 33 to be opened, and the cleaning liquid in the pump shell 28 is sprayed out of the liquid outlet pipeline 32 and the liquid spraying port 14.

[0090]

[0091] ​​In this embodiment, the housing 18 includes a front housing 40 and a rear housing 41, which together form a liquid storage cavity 13. A partition 42 is integrally formed on the rear housing 41, which divides the rear housing 41 into upper and lower parts. The lower part of the rear housing 41 forms the liquid storage cavity 13, and the upper part of the rear housing 41 forms an area for installing the pressing part 12. The middle part of the partition 42 extends into the liquid storage cavity 13 to form a pump housing 28 integrally formed with the rear housing 41. The inlet 36, outlet 37 and the hole for installing the pump core 29 on the pump housing 28 connect the upper and lower parts of the rear housing 41.

[0092] In this embodiment, both the inlet valve 31 and the outlet valve 33 are duckbill valves, and the mouths of the two duckbill valves face opposite directions.

[0093] Preferred, such as Figure 14 A reinforcing ring 44 is provided slightly inward from the outer periphery of the front shell 40. When the front shell 40 and the rear shell 41 are installed, the reinforcing ring 44 is inserted into the rear shell 41 and fits the surface of the rear shell 41. After installation, the front and rear shells 41 have two sets of approximately perpendicular mating surfaces 45. The two sets of mating surfaces 45 work together to prevent the cleaning fluid in the liquid storage chamber 13 from leaking out. To further prevent leakage, adhesive, sealing accessories, or welding can be used between the mating surfaces 45.

[0094] In other embodiments, the structures of the front shell 40 and the rear shell 41 can be interchanged. For example, the partition 42 and the pump shell 28 are integrally formed on the front shell 40, and the rear shell 41 is provided with a reinforcing ring 44, which is inserted into the front shell 40 and adapted to the surface of the front shell 40.

[0095] Preferably, the second type of liquid pump 27 has the following structure: the liquid pump 27 includes a pump housing 28, a pump core 29, a seal 46, a moving part 47, an inlet valve 31, and a spring 35. The pump housing 28 has two open ends for inlet and outlet liquid respectively. The inlet 36 has a constricted section 48 with a smaller diameter than other parts of the pump housing 28. The inlet valve 31 is installed downstream of the constricted section 48. The seal 46 is fixedly installed at one end of the outlet 37, and a first connecting element is located at the center of the seal 46. The first connecting hole 49 has a first interlayer 50 and a second interlayer 51 on its outer side. The pump core 29 and the movable part 47 are respectively installed at the upstream and downstream positions of the first connecting hole 49. The movable part 47 has a through second connecting hole 52, and the pump core 29 has a through third connecting hole 53. The downstream of the pump core 29 is inserted into the second connecting hole 52 for installation, so that the second connecting hole 52 and the third connecting hole 53 are connected. The downstream of the second connecting hole 52 is connected to the spray nozzle 14 through the liquid outlet pipe 32.

[0096] The operating principle of this liquid pump 27 is as follows:

[0097] In the spraying state, the movable member 47 is pressed to drive the pump core 29 to move upstream, the third connecting hole 53 is separated from the sealing member 46 to communicate the second connecting hole 52 and the cavity in the pump shell 28, the movable member 47 and the pump core 29 continue to move upstream until the sealing member 46 is synchronously moved to extrude the cavity volume of the pump shell 28, in the process of the cavity volume of the pump shell 28 being reduced, the liquid inlet valve 31 blocks the liquid inlet 36, the cleaning liquid in the pump shell 28 cannot flow back to the liquid storage cavity 13, but can only flow out through the second connecting hole 52, the third connecting hole 53, the liquid outlet pipeline 32 and the spraying port 14;

[0098] In the liquid inlet state, the spring 35 is released to drive the pump core 29 and the movable member 47 to move downstream synchronously, the third connecting hole 53 is blocked by the sealing member 46, the second connecting hole 52 and the cavity in the pump shell 28 are blocked, the pump core 29 and the movable member 47 continue to move downstream until the sealing member 46 is synchronously moved to increase the cavity volume of the pump shell 28, in the process of the cavity volume of the pump shell 28 being increased, the liquid pressure or the gas pressure on the upstream and downstream sides of the liquid inlet valve 31 is different, the cleaning liquid in the liquid storage cavity 13 pushes the liquid inlet valve 31 to move downstream and open the liquid inlet 36, the cleaning liquid is supplemented into the cavity of the pump shell 28, and after the pump core 29, the sealing member 46 and the movable member 47 move to the initial position, the liquid inlet of the pump shell 28 is completed.

[0099] Preferably, the sealing member 46 is provided with a thin wall 54 outside the first interlayer 50 and the second interlayer 51, the thin wall 54 is in the shape of a bell mouth, in the process of the sealing member 46 moving in different directions, the liquid pressure or the gas pressure in the cavity of the pump shell 28 makes the thin wall 54 at different positions deform and fit the inner wall of the pump shell 28, so as to avoid the pump shell 28 from leaking gas or liquid.

[0100] In the embodiment, the upstream and the downstream refer to the relative position of the flow direction of the liquid in the liquid storage cavity 13 flowing to the spraying port 14 through the liquid pump 27, which is independent of the installation direction of the spraying mechanism 7 and the installation direction of the liquid pump 27, that is, no matter what the direction of the spraying mechanism 7 and the liquid pump 27 is, the direction of the cleaning liquid flowing out of the liquid storage cavity 13 is fixed, and the flow direction of the cleaning liquid in the embodiment is the liquid storage cavity 13, the liquid inlet pipeline 30, the pump shell 28, the liquid outlet pipeline 32 and the spraying port 14 in sequence.

[0101] Preferably, the third liquid pump 27 is an electric pump, which is installed in or outside the liquid storage cavity 13, and is connected with the spraying port 14 to drive the cleaning liquid in the liquid storage cavity 13 to the spraying port 14 to be sprayed out. Embodiment 3

[0102] The difference between the embodiment and the embodiment 2 is that the spraying mechanism 7 does not separately provide the liquid pump 27.

[0103] In the embodiment, the first liquid outlet mode is that, as shown in FIG. 1, the liquid outlet pipeline 32 is connected with the liquid inlet pipeline 30 and the pump shell 28, and the liquid outlet pipeline 32 is connected with the spraying port 14. Figure 18The liquid spraying mechanism 7 comprises a pressing part 12, a shell 18, and a liquid spraying port 14. A cavity in the shell 18 forms a liquid storage cavity 13. The liquid spraying port 14 is located at the bottom of the shell 18. The top of the shell 18 is open. The pressing part 12 is provided as a push rod, and the lower end is inserted into the liquid storage cavity 13. The cleaning liquid is squeezed out of the liquid storage cavity 13 by moving the pressing part 12 downward in the liquid storage cavity 13.

[0104] In the second liquid spraying mode in the embodiment, the liquid spraying mechanism 7 comprises a pressing part 12, a shell 18, a liquid spraying port 14, and a liquid spraying valve 55. Specifically, a cavity in the shell 18 forms a liquid storage cavity 13. The liquid spraying port 14 is arranged at a low position of the liquid storage cavity 13. A liquid inlet 38 of the shell 18 is detachably connected with a sealing plug 39. After the liquid spraying mechanism 7 is installed, the shell 18 is sealed, that is, the liquid spraying valve 55 can prevent the cleaning liquid from flowing out when the shell 18 is rotated to any angle. The pressing part 12 is made of flexible material. The volume of the liquid storage cavity 13 is reduced by deforming the pressing part 12 into the liquid storage cavity 13 through pressing the pressing part 12, so that the air pressure difference is formed between the liquid storage cavity 13 and the outside. The liquid spraying valve 55 is opened by the air pressure difference and sprays liquid outward. When the pressing part 12 is released, the pressing part 12 is deformed outward and returns to the original position. The internal air pressure of the liquid storage cavity 13 is less than the external air pressure after spraying liquid. The air pressure difference between the inside and outside of the liquid storage cavity 13 causes the liquid spraying valve 55 to open and supplement air into the liquid storage cavity 13 until the air pressure inside and outside the liquid storage cavity 13 is balanced.

[0105] Preferably, as Figure 19 , the liquid spraying mechanism 7 can be configured that the shell 18 is made of hard plastic, the pressing part 12 is made of flexible material, and the shell 18 and the pressing part 12 are connected in a sealed manner; as Figure 20 , the liquid spraying mechanism 7 can also be configured that the shell 18 is made of flexible material as a whole. The surface of the shell 18 is provided with a position for pressing and deforming to form the pressing part 12, so as to realize the liquid spraying by changing the air pressure through pressing. Figure 21 , the liquid spraying mechanism 7 can also be configured that the shell 18 is provided as a telescopic folding structure as a whole. The surface of the shell 18 is provided with a position for pressing and telescopic folding to form the pressing part 12, so as to realize the liquid spraying by changing the air pressure through pressing.

[0106] Further, as Figure 22 , the shell 18 is made of hard plastic, the pressing part 12 is made of flexible material or provided as a telescopic folding structure, and the pressing part 12 is communicated with the shell 18 through an air pipeline 56. The pressing part 12 is pressed outside the shell 18. The air in the pressing part 12 enters the liquid storage cavity 13 through the air pipeline 56 to squeeze the cleaning liquid out of the liquid spraying port 14. Embodiment 4

[0107] The difference between the embodiment and the embodiment 3 is the structure of the installation platform 19.

[0108] In the embodiment, the mounting platform 19 refers to a device for fixing the connection of the flat mop and the liquid spraying mechanism 7 as a whole. The mounting platform 19 can be arranged on the flat mop, on the liquid spraying mechanism 7, or on both the flat mop and the liquid spraying mechanism 7. After the flat mop and the liquid spraying mechanism 7 are installed, the device for fixing is combined to form the mounting platform 19.

[0109] In the embodiment, the flat mop and the liquid spraying mechanism 7 are two independent individuals during production and processing. After the components of the liquid spraying mechanism 7 are formed, installed, and integrated into a complete liquid spraying module, the liquid spraying mechanism 7 is installed with the flat mop to improve the production, installation, and inspection efficiency of the liquid spraying mechanism 7 and reduce the replacement and scrap costs of the liquid spraying mechanism 7 and the flat mop due to unqualified water test.

[0110] The mounting platform 19 in the embodiment can be implemented in various structures. In some structures, the mounting platform 19 makes the liquid spraying mechanism 7 no longer need to be used with a specially designed flat mop. The mounting platform 19 makes the liquid spraying mechanism 7 adaptable to the flat mop on the market and purchased by the user, so that the application range of the liquid spraying mechanism 7 is wider.

[0111] Preferably, the first mounting platform 19 is arranged as follows: Figures 23-24 The upper part of the water squeezing sleeve 5 is provided with an outwardly protruding raised frame 57. The outer end of the raised frame 57 is flush. The inner side wall of the raised frame 57 is provided with a first protrusion 58 in an L shape. The two directionally extended arms of the first protrusion 58 form a slot 59. The housing 18 of the liquid spraying mechanism 7 is provided with an extension table 60. The side surface of the extension table 60 is provided with a second protrusion 61. During installation, the first protrusion 58 and the second protrusion 61 are misaligned. The extension table 60 is inserted into the raised frame 57. The liquid spraying mechanism 7 is rotated in a predetermined direction to make the second protrusion 61 enter the slot 59 formed by the first protrusion 58, thereby realizing the quick installation and disassembly of the liquid spraying mechanism 7. In this way, the raised frame 57 and the extension table 60 jointly form the mounting platform 19.

[0112] More specifically, the frame 57 is square, and each of the two opposite inner side walls of the frame 57 is provided with a first protrusion 58, and the two first protrusions 58 are centrally symmetric. The extension platform 60 is circular, and the diameter of the extension platform 60 is smaller than the length of the smallest side of the frame 57. During installation, the second protrusion 61 is aligned with the corner position of the frame 57, and the extension platform 60 is inserted into the frame 57 until the extension platform 60 abuts against the frame 57. At this time, the liquid spraying mechanism 7 can be rotated to position the second protrusion 61 into the insertion slot 59. The square shape of the frame 57 provides a corner area of the frame 57 for the insertion of the second protrusion 61 to form an installation positioning point. That is, other positions except the corners will abut against the second protrusion 61 to prevent the second protrusion 61 from being inserted into the frame 57, thereby simplifying the positioning during installation of the liquid spraying mechanism 7. In addition, in order to avoid the insertion of the second protrusion 61 aligned with the corner away from the insertion slot 59, in the embodiment, the corner position away from the insertion slot 59 is also provided with a foolproof position 62, which is realized by setting a shape different from that of the other corner, setting an identification, or setting a blocking block.

[0113] Of course, in other embodiments, such as Figure 25 , the insertion slot 59 in the form of L can be provided on one of the frame 57 and the extension platform 60, and the second protrusion 61 can be provided on the other one, and the installation positioning is realized by aligning the second protrusion 61 with the outer end of the insertion slot 59.

[0114] Preferably, the second installation platform 19 is provided as follows: Figure 26 The upper part of the water squeezing sleeve 5 is provided with the frame 57, the inner side wall of the frame 57 is provided with an internal thread 63, the shell 18 is provided with the extension platform 60, the side surface of the extension platform 60 is provided with an external thread 64, the frame 57 and the extension platform 60 together constitute the installation platform 19, and during installation, the liquid spraying mechanism 7 is rotated to be threadedly connected with the extension platform 60.

[0115] Preferably, the third installation platform 19 is provided as follows: Figure 27 The upper part of the water squeezing sleeve 5 is provided with the frame 57, the inner side wall of the frame 57 is provided with a male buckle 65, the shell 18 is provided with the extension platform 60, the side surface of the extension platform 60 is provided with a female buckle 66, the frame 57 and the extension platform 60 together constitute the installation platform 19, and during installation, the liquid spraying mechanism 7 is pressed to be buckled connected with the extension platform 60.

[0116] Preferably, the fourth installation platform 19 is provided as follows: one or both of the water squeezing sleeve 5 and the shell 18 is provided with the extension platform 60, and the water squeezing sleeve 5 and the liquid spraying mechanism 7 are fixedly connected by installing a screw on the extension platform 60.

[0117] In the above embodiments, all four mounting platforms 19 are configured as detachable structures, allowing the spraying mechanism 7 to be fixedly installed and used in conjunction with the flat mop to spray liquid onto the wiping material 3. Alternatively, the flat mop and the spraying mechanism 7 can be used independently after the spraying mechanism 7 is disassembled. Simultaneously, the raised or extended portions on the mounting platform 19 allow the spraying mechanism 7 to suspend outside the wringer sleeve 5, enabling the upper ends of the mop head 2 and the wiping material 3 to be inserted into the gap between the spraying mechanism 7 and the wringer sleeve 5 for positioning or spraying.

[0118] In other embodiments, the water squeezing sleeve 5 and the spraying mechanism 7 can be connected in a non-detachable structure by means of riveting, welding, or other methods, based on the use of the frame 57 and the extension platform 60.

[0119] All of the above-mentioned installation platforms 19 require specially made wringer sleeves 5 to install the spraying mechanism 7. In order to facilitate the use of the spraying mechanism 7 with ordinary wringer sleeves 5 and ordinary mops, in this embodiment, the installation platform 19 can also be set on the spraying mechanism 7 as a whole.

[0120] Specifically, such as Figure 28 The housing 18 of the spray mechanism 7 is provided with an extension platform 60. The extension platform 60 is equipped with clamps, rings 67, straps, tube clamps, cable ties, Velcro straps, and other clamping structures. These clamping structures fix the spray mechanism 7 to a regular mop or wringer 5 by wrapping around the mop handle 1 or wringer 5. The elasticity and tightness of the clamping structures can be adjusted to fix the spray mechanism 7 to mops or wringer 5 of different sizes. The extension platform 60 and the clamping structures together form an installation platform 19. The clamping structures are used to install the spray mechanism 7 on the mop, and the extension platform 60 is used to control the distance between the spray mechanism 7 and the mop handle 1 and wringer 5 to avoid protruding parts on the mop affecting the installation of the spray mechanism 7. It also facilitates the mop head 2 and the wiping material 3 to enter the gap between the spray mechanism 7 and the mop handle 1 or wringer 5 for positioning and spraying. Even if the installed mop is not equipped with a wringer 4, the installed spray mechanism 7 can spray liquid onto the wiping material 3, and then place the wiping material 3 on the mop bucket or other cleaning devices for cleaning, thereby expanding the range of mops that can be used with the spray mechanism 7.

[0121] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
